After 2 years of engineering work and rigorous testing, the all new Turbine rings are ready to ride. Completely redesigned from the ground up, these rings shift like nothing else. As with our previous Team and Race rings, the Turbine rings are made in Canada from 7075 aluminium, so they are built to last. Aside from their stunning good looks, these are the highlights:Offering unparalleled form and function, the new Turbine rings are second to none, and come standard on our Deus and Next cranks. Features:• New asymmetrical tooth profiling and more upshift and downshift zones yield instantaneous smooth and quiet shifting, even under load. • 3 times stiffer than our previous Team chainrings without any weight gain. Net result is much sharper, quicker and more responsive shifts as well as increased resistance to impacts. • Machined in Canada with US made aluminium.
